Disable some functionalities if any UI button is missing

Question

Hi,

I have gotten a use case where if button in an Addin UI is missing somehow  I have to disable other functionalities. So basically if that button is not visible in the UI then how to disable other functionalities dependent on that button because I don't want user to use those functionalities.

Any help!

@GKmieliauskas is quite correct as you need to implement your own states and conditions to control your Add-in's UI. There is a ProGuide to states and conditions here: ProGuide Code Your Own States and Conditions · Esri/arcgis-pro-sdk Wiki (github.com) Then in your add-in's module class you can check for the existence of the needed Add-in using the FrameworkApplication API: var theNeededModule = FrameworkApplication.FindModule("NeededModule"); The Module ID "NeededModule" can be found in the Add-in module's config.daml file: ... If theNeededModule value is null the needed add-in is not available otherwise the needed add-in is available. You can use that value to control your states and conditions.

Yes Addin not installed can be an only use case I can think of.

Can you elaborate why a button would be missing from the UI?  Is the Add-in not installed ?   If the Add-in is installed why would the button be missing?   I don't understand your use case for this.
